Hello & Welcome to JA,



The electronic suspension control module requests that the message be displayed via class 2 serial data message. The message indicates that the road sensing suspension system has set a DTC.


Road Sensing Suspension General Description

Attachments are only available to registered users.

Register Here

The Continuously Variable Road Sensing Suspension (CVRSS) system consists of the following components: Electronic Suspension Control (ESC) module (3), four dampers contained in the two front struts (5 and 6) and the two rear shock absorbers (1 and 9), four positions sensors (2,4,7, and 8), ALC air compressor module (10), Damper relay (not shown), and ALC relay (not shown).

The Continuously Variable Road Sensing Suspension (CVRSS) system with rear Automatic Leveling Control (ALC) controls damping forces in the front struts and rear shock absorbers in response to various road and driving conditions. The rear ALC portion of the system maintains a proper vehicle trim height under various vehicle load conditions.

NOTE: The Electronic Suspension Control (ESC) module will remain powered for a short period of time (typically under 5 minutes) after the ignition has been turned off. This system-on period after ignition-off allows the system to level and perform other required functions.

The Electronic Suspension Control (ESC) module receives the following inputs: wheel-to-body position, vehicle speed, and lift/dive. The Electronic Suspension Control (ESC) module evaluates these inputs and controls actuators in each of the dampers independently to provide varied levels of suspension control.

The description of the system does not tell me what the message there a way to access codes or some other way to find out what the problem will the car be s safety hazard in this mode??? its a 2000 cadillac north star etc


This message means there is a fault code set in the computer ,a scan tool with the proper software to access data from the electronic suspension control module is needed to view the fault code & current data.

This is NOT a safety hazard.
